Fluid sandwich crab stick cutting device and cutting method thereof

Abstract

The invention discloses a fluid sandwich crab stick cutting device and a cutting method thereof, and relates to the technical field of cutting devices. Comprising a cutting-off cutter body used for rotationally cutting off a fluid sandwich crab stick body, the cutting-off cutter body comprises a sheath part, a cutting edge part and a carrying part, the cutting edge part is integrated in the sheath part, and the cutting edge part and the sheath part are jointly installed outside the carrying part and pop out only before the fluid sandwich crab stick body is cut off. In the cutting process, high temperature on the surface when the cutting edge piece pops up promotes protein on the outer layer of minced fillet to be rapidly denatured and solidified to form a heat sealing layer, and meanwhile, low temperature emitted by the sheath piece acts on stuffing fluid through the sheath opening isolation layer, so that the viscosity of the stuffing fluid is improved; the problem that shearing stress waves of a traditional cut-off device are uneven in transmission is effectively solved through a double-temperature-control mechanism, and fluid sandwich leakage in the fluid sandwich crab sticks is relieved.

Description

Technical Field

[0001] The present invention relates to the technical field of cutting devices, and particularly to a fluid sandwich crab stick cutting device and a cutting method thereof. Background Art

[0002] "Fluid sandwich crab stick" is an innovative food that combines traditional crab stick (surimi product) with a flowing filling. It is commonly found in the catering industry or in home creative cooking. During its production process, co-extrusion technology is often used to directly inject the fluid filling during the formation of surimi, and a cutting device is used for fixed-length cutting. However, when dealing with such multi-layer composite structures, general cutting devices are prone to uneven shear stress, resulting in filling leakage or surimi deformation, making the product quality uneven, affecting the taste and appearance. To address this technical problem, the present invention proposes a fluid sandwich food ingredient device and a cutting method thereof.

[0003] After retrieval, the Chinese invention patent with the publication number "CN113729178A" discloses a "demolding and cutting device for crab stick". The servo motor drives the cutting member to rotate, so that the cutting member cuts the crab stick during rotation. During the cutting process, since the cutting edge of the cutting member is arc-shaped, the cutting member can cut the meat inside the crab stick without cutting the outer membrane of the crab stick.

[0004] In addition, the Chinese invention patent with the publication number "CN117817736A" discloses a "cutting device for processing sandwich crab patties". The swing assembly drives the swing frame and the extension frame to perform reciprocating swings, so that the cutter can swing to cut the sandwich crab patties transported to the bearing plate. After each cutting action on the sandwich crab patties, the scraping component can drive the scraping sleeve plate to slide reciprocally relative to the cutter once, to scrape off the filling slurry contaminated on the cutter, effectively avoiding the filling slurry splashing onto the surface of the sandwich crab patties during the cutting process, and greatly improving the cutting quality of the sandwich crab patties.

[0005] However, it should be noted that although the above two existing technologies and similar devices can achieve the cutting of crab sticks or the cutting of sandwich crab patties, when dealing with food ingredients with multi-layer composite structures such as fluid sandwich crab sticks, due to the special combination method of the fluid filling and the surimi outer layer of the fluid sandwich crab sticks, when processing fluid sandwich crab sticks, the fluid filling will ooze out instantaneously during cutting, thus affecting the appearance and internal quality of the final product. In view of this, the present invention aims to design a cutting device customized for fluid sandwich crab sticks. Summary of the Invention

[0006] The purpose of the present invention is to provide a fluid sandwich crab stick cutting device and a cutting method thereof to solve the problems raised in the above background art.

[0007] To achieve the above purpose, the present invention provides the following technical solutions: In a first aspect, a cutting device for fluid-filled crab sticks is proposed, comprising: A cutting blade body for rotationally cutting the fluid-filled crab stick body; The cutting blade body includes a sheath member, a blade member, and a mounting portion. The blade member is integrated within the sheath member, and they are jointly installed outside the mounting portion and only pop out before cutting the fluid-filled crab stick body. The sheath member and the blade member respectively generate cold energy and heat energy. During cutting, the heat energy on the surface of the blade member accelerates the cutting of the fluid-filled crab stick body, and the cold energy on the surface of the sheath member plastifies the filling fluid within the fluid-filled crab stick body, ensuring a flat cross-section of the fluid-filled crab stick body and sealing the internal fluid; The mounting portion includes: A collar box with an energy supply component capable of transmitting current installed around its periphery. There are two collar boxes. The two collar boxes respectively install the sheath member and the blade member through the energy supply component. The contact surfaces of the two collar boxes are fixed, and the other side of the two collar boxes is used to receive electrical energy. The ring opening within the collar box is used to receive rotational energy; A trigger sleeve fixed in position within the collar box for installing the blade member by means of an external connection is inserted into the collar box for installing the blade member. A protruding contact ball is fixed to the outside of the trigger sleeve. During the rotation of the collar box for installing the blade member, the bottom of the blade member pops out from the sheath member by contacting the contact ball.

[0008] As a further preferred embodiment of this technical solution, the external connection includes: a cover body and a transmission component. The cutting blade body is assembled outside the cover body and internally inserted with the transmission component. The transmission component is used to transmit driving energy and limit and fix the trigger sleeve. The driving energy includes: rotational energy and electrical energy; The transmission component is installed outside the crab stick conveyor through an assembly component. When the fluid-filled crab stick body carried on the surface of the crab stick conveyor is continuously conveyed, the assembly component transmits the driving energy of the transmission component to drive the cutting blade body to perform a rotary motion along the periphery of the cover body, thereby completing the cutting and separating operation of the fluid-filled crab stick body.

[0009] As a further preferred embodiment of this technical solution, the structure of the collar box varies according to the different functional regions for installing the blade member and the sheath member; A through rod for contacting the contact ball and serving as the bottom of the blade member is inserted through a placement opening formed on the outer surface of the collar box for installing the blade member. A return spring integrated outside the collar box is installed on the outer surface of the through rod. The other end of the through rod is hinged to a connecting folding rod, and the folding end of the connecting folding rod is fixed to the surface of the blade member; The outer surface of the collar box for installing the sheath member is directly fixed to the bottom end of the sheath member.

[0010] As a further preference of the present technical solution, there is an electrical connection relationship between the energy supply component and the transmission component. The structure of the energy supply component presents differentiated characteristics due to the installation requirements of the blade component and the scabbard component. When adapting to the blade component, the composition structure of the energy supply component includes: A functional seat, inside which there is a rod-shaped interface adapted to the insertion rod. The composition of the rod-shaped interface differentiates the characteristic quantities of the energy supply components adapted to the scabbard component and the blade component; The functional seat forms a sliding fit with the external slide rail of the cover through a chute provided on one side of the bottom. The other side of the bottom of the functional seat is rigidly connected to the collar box through a conductive arm. A conductive cover that forms a conductive circuit with the conductive arm is integrated on the surface of the collar box. There is an electrical connection relationship between the conductive cover and the transmission component.

[0011] As a further preference of the present technical solution, the scabbard component includes: A scabbard, the outside of the scabbard mouth is designed with a sharp edge, and an insulating layer is laid on the inside of the scabbard mouth. The insulating layer is used to isolate the temperature exchange between the scabbard and the blade. An arc-shaped notch that bends along the scabbard mouth position is opened at the central axis position on one side of the surface of the scabbard, and the arc-shaped notch is adapted to the connecting folding rod; The blade component includes: A blade, slidably connected in the scabbard, the cutting edge of the blade is aligned with the scabbard mouth, and a contact frame is fixed on the back edge of the blade. The surface of the contact frame is fixed to the connecting folding rod.

[0012] As a further preference of the present technical solution, the transmission component includes: A main transmission shaft and a secondary transmission shaft, respectively inserted into the two collar boxes. The secondary transmission shaft is installed in the collar box where the blade component is installed, and one end of the secondary transmission shaft is hinged to one end of the main transmission shaft, and the outer periphery of one end of the secondary transmission shaft is fixed to the inner wall of one end of the trigger sleeve. The other end of the trigger sleeve does not contact the inner wall of the collar box where the blade component is installed; The surfaces of the contacting ends of the main transmission shaft and the secondary transmission shaft are fixed to the inner wall of the collar opening of the collar box where the scabbard component is installed. The other ends of the main transmission shaft and the secondary transmission shaft are jointly fixed to both ends installed on the inner wall of the assembly component.

[0013] As a further preference of the present technical solution, conductive tubes are sleeved outside the surfaces of the main transmission shaft and the secondary transmission shaft. One end of the conductive tube is fixed to the inner wall of the assembly component, and an insulating cover is sleeved outside the conductive tube; A power supply seat is installed at the position of the conductive tube in the cover body, and a rigid connecting conductive bundle is installed between the power supply seat and the conductive cover.

[0014] As a further preference of the present technical solution, the assembly component includes: The connecting frame is fitted and fixed at one end outside the crab stick conveyor. One side at the top of the inner wall of the connecting frame is fixedly connected to the secondary transmission shaft, and a servo motor is installed on the other side at the top of the inner wall of the connecting frame. The shaft body of the servo motor penetrates through the connecting frame and is fixedly connected to one end of the main transmission shaft; On the surface of the connecting frame near the position of the crab stick conveyor, a splash-proof arc plate for covering the outside of the crab stick conveyor is laid and fixed. A retention gap for the cutting blade body to rotate is left between the two splash-proof arc plates. At the bottom end inside the connecting frame, a reinforcement arm is fixed which fits against the bottom of one end outside the crab stick conveyor.

[0015] Secondly, to improve the above technical solution, a cutting method for a fluid sandwich crab stick cutting device is also proposed, which uses any one of the fluid sandwich crab stick cutting devices disclosed above.

[0016] Compared with the prior art, the beneficial effects of the present invention are: In the cutting process of the fluid sandwich crab stick cutting device and its cutting method, the high temperature on the surface when the blade member pops out promotes the rapid denaturation and solidification of the protein on the outer layer of the surimi, forming a heat-sealing layer. At the same time, the low temperature emitted by the knife sheath member acts on the inner filling fluid through the sheath mouth isolation layer, increasing its viscosity. With a dual temperature control mechanism, it effectively overcomes the problem of uneven transmission of shear stress waves in traditional cutting devices, and reduces the leakage of the fluid filling in the fluid sandwich crab stick; In addition, when the secondary transmission shaft triggers the blade member to complete the pop-out - cutting through the contact ball and then reset under the action of the return spring, it ensures the phase lag problem existing in the rotary cutting process and improves the processing efficiency to a certain extent; It should also be added that through the linkage cooperation between the transmission component and the shaft body of the servo motor, while the crab stick conveyor evenly conveys the fluid sandwich crab stick body, the centrifugal force generated by the rotation of the trigger sleeve through the sleeve ring box collides with the contact ball to form a periodic trigger signal, so that the blade member pops out when the cutting phase angle reaches the preset position, ensuring the uniformity of each cutting interval.

Specific implementation manner

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Before understanding the technical solution proposed in this application, it should be clear that in this application, the principles of heating and cooling of the blade member and the scabbard member are respectively achieved through the electrical connection between the energy supply component and the conductive tube 502. Specifically, a semiconductor heating element is provided in the function seat 608 for installing the blade member, which receives the pulsed current conducted by the conductive tube 502 through the conductive arm 602, enabling the surface of the blade member to have the ability to increase temperature. The function seat 608 for installing the scabbard member integrates a micro-compressor refrigeration module, and the surface temperature of the scabbard member is maintained in the range of -5°C to 5°C through the power supply circuit of the conductive arm 602. It should be noted that in this application, since both the semiconductor heating element and the micro-compressor refrigeration module are common devices in the prior art, this application is integrated inside the function seat 608 and is not shown separately.

[0021] In addition, it should be noted that in this application, the isolation layer inside the scabbard member is made of a nano-ceramic composite material with a thermal conductivity coefficient lower than 0.8 W / (m·K). Under the working condition where the distance between the scabbard 603 and the blade 609 is 0.2 - 0.5 mm, a temperature difference gradient exceeding 100°C / mm can be maintained. When the transmission component 5 drives the cutting blade body 6 to rotate, every time the trigger sleeve 505 rotates to the phase angle where it collides with the contact ball, the blade member pops out of the scabbard member to complete the cutting action. At this time, the high temperature of the blade 609 forms a dense protein coagulation layer on the surface of the surimi, while the low-temperature field of the scabbard 603 increases the viscosity of the inner filling fluid, realizing the "heat sealing - condensation" double curing effect.

[0022] It should be further noted that when the servo motor 305 drives the main transmission shaft 503 to rotate, the positive current forms a heating circuit through the conductive tube 502 → the energy supply seat 506 → the conductive cover 605 → the conductive arm 602, and the refrigeration circuit of the scabbard member is realized through an independently laid Freon circulation pipeline, and this pipeline is arranged on the inner wall of the scabbard 603 to form a closed-loop cooling system.

[0023] As Figures 1 - 11 shown, the present invention provides a technical solution: a fluid sandwich crab stick cutting device, including: A cutting blade body 6 for rotating to cut the fluid sandwich crab stick body 4.

[0024] It should be noted that in this application, the cutting tool body 6 includes three core components: a sheath member, a blade member, and a mounting portion. Among them, the blade member is integrated into the internal cavity of the sheath member in an embedded structure, and the two form a coaxial assembly relationship through precision cutting technology and are jointly installed outside the mounting portion. It is worth noting that in this application, the blade member only pops out in the form of mechanical linkage before cutting the fluid-filled crab stick body 4. The internal surface of the sheath member maintains a low-temperature field of -5°C to 0°C through an integrated semiconductor cooling module, while the blade member maintains a constant-temperature thermal field of 120°C ± 5°C through a resistance heating element. During the cutting operation, the high temperature on the surface of the blade member can instantaneously melt the protein fiber structure of the fluid-filled crab stick body 4, and at the same time, the low-temperature field of the sheath member solidifies and plastifies the internal filling fluid, ensuring that the cross-section of the fluid-filled crab stick body 4 forms a flat section and realizing the microcapsule encapsulation of the internal fluid through the dual action.

[0025] It should be supplemented that the mounting portion of this application adopts a modular assembly design, specifically including a collar box 601. The collar box 601 is cast from aluminum alloy. It should also be noted that in this application, the two configured collar boxes 601 are arranged in a mirror-symmetrical layout. The contact surfaces of the two collar boxes 601 are permanently fixed by a vacuum diffusion welding process. The non-contact surfaces are respectively provided with waterproof power supply interfaces that meet the IP68 standard, and a conductive cover 605 is installed at this interface.

[0026] It is worth noting that the mechanical linkage provided in the inner cavity of the collar box 601 for installing the blade member is a trigger sleeve 505 that is fixed in position in the collar box 601 by means of an external connecting object. A protruding contact ball is fixed outside the trigger sleeve 505. During the rotation of the collar box 601 for installing the blade member, the bottom of the blade member pops out from the sheath member by contacting the contact ball.

[0027] It should be noted that in this application, the external connecting object includes: a cover body 7 and a transmission assembly 5. Refer to Figure 7 It can be seen that the cover body 7 is specifically in the structural form of a heat dissipation cover 701 and is used for dissipating heat from the cutting tool body 6.

[0028] The cutting tool body 6 is assembled outside the cover body 7, and the transmission assembly 5 is inserted inside. The transmission assembly 5 is used to transmit driving energy and limit and fix the trigger sleeve 505. The driving energy includes: rotational energy and electrical energy.

[0029] It should be supplemented that in this application, the transmission assembly 5 is installed outside the crab stick conveyor 2 through an assembly component 3. When the fluid-filled crab stick body 4 carried on the surface of the crab stick conveyor 2 is continuously conveyed, the assembly component 3 drives the cutting tool body 6 to perform a rotary motion along the periphery of the cover body 7 through the transmission of the driving energy of the transmission assembly 5, thereby completing the cutting and separating operation of the fluid-filled crab stick body 4.

[0030] It should be further noted that in this application, the crab stick conveyor 2 is a transmission device in the prior art, and its core components include: a driving motor 201, a belt conveyor 202, a limiting rod 203, a belt transmission group 204, a gear matching group 205, and a mounting frame 206. It should be added that a control panel 1 is installed outside the belt conveyor 202, and the control panel 1 is used to control the operation of the driving motor 201, the servo motor 305, and the function seat 608.

[0031] Specifically, the driving motor 201 is fixed to the side wall of the frame by means of flange connection, and its output shaft is connected to the main driving roller shaft end of the belt conveyor 202 through an elastic coupling to provide the basic power source for the whole machine. The belt conveyor 202 adopts a food-grade polyurethane synchronous belt structure with anti-slip convex patterns on the surface, effectively improving the conveying stability of crab stick products. It should be noted that the belt transmission group 204 is installed in parallel on the right transmission end of the belt conveyor 202 through a processed aluminum alloy bracket, and its driving wheel forms a transmission with the side transmission shaft of the belt conveyor 202, thereby obtaining the rotational energy of the driving motor 201. Refer to Figure 1 and Figure 2 the shown structure. The driven wheel end of the belt transmission group 204 is sleeved on the outer periphery of the limiting rod 203 arranged in the middle section outside the belt conveyor 202. The limiting rod 203 is made of stainless steel and is provided with an axial adjustment thread, which can not only ensure the tension of the transmission belt but also realize the fine-tuning function of the transmission path. Through this special design, the belt transmission group 204 can synchronously drive the gear matching group 205 rigidly connected to the double-row belt pulley inside it to rotate. It should be emphasized that the extended part at the end of the limiting rod 203 is equipped with a mounting frame 206, and the bushing part of the mounting frame 206 is nested with the main driving gear of the gear matching group 205. The outer edge of the main driving gear is fixed with a pressing roller through interference fit, and the surface of the pressing roller is treated by hard anodizing. Under the drive of the gear matching group 205, the continuous and uniform pressing operation of the core crab stick is completed.

[0032] It should be further emphasized that since the crab stick conveyor 2 is a specific existing device, in this application, the detailed structure inside the crab stick conveyor 2 is not further shown and described in the drawings.

[0033] It should also be added that in this application, the structure of the collar box 601 varies according to the different functional areas of the installed cutting blade part and the knife sheath part.

[0034] Specifically, the outer surface of the collar box 601 for installing the blade member is inserted and installed with an insertion rod 611 that is used to contact the contact ball and serves as the bottom of the blade member through the placed opening 606 provided. The insertion rod 611 is precision machined from high-strength alloy steel, and a return spring 612 integrated outside the collar box 601 is installed on the outer surface by an interference fit method. The return spring 612 is wound with 60Si2Mn spring steel with a wire diameter of 1.2 mm, and the compression stroke reaches 8 mm. The other end of the insertion rod 611 is connected to a connecting folding rod 610 through a precision hinge structure. The folding end of the connecting folding rod 610 is rigidly connected to the surface of the blade member through a laser welding process, and its unfolding angle can be finely adjusted through a matching limit groove.

[0035] In addition, it should be noted that in this application, the outer surface of the collar box 601 for installing the scabbard member is directly fixed to the bottom end of the scabbard member.

[0036] As a preferred implementation manner, an electrical connection relationship is established between the energy supply component and the transmission assembly 5. In order to adapt to the installation requirements of the blade member and the scabbard member, the structure of the energy supply component presents a differentiated feature. When adapting to the blade member, the composition structure of the energy supply component includes: A function seat 608, which is internally provided with a rod-shaped interface adapted to the insertion rod 611. The composition of the rod-shaped interface distinguishes the characteristic quantity of the energy supply components for the scabbard member and the blade member, where the characteristic quantity specifically represents the basis for differentiation.

[0037] In addition, in this implementation manner, the function seat 608 forms a sliding fit with the external slide rail 702 of the cover body 7 through a chute 607 provided on one side of the bottom. The other side of the bottom of the function seat 608 is rigidly connected to the collar box 601 through a conductive arm 602. A conductive cover 605 that forms a conductive circuit with the conductive arm 602 is integrated on the surface of the collar box 601. There is an electrical connection relationship between the conductive cover 605 and the transmission assembly 5, ensuring the electrical continuity of the entire system.

[0038] As a preferred implementation manner, referring to Figures 7 - 11 it can be seen that in this implementation manner, the scabbard member includes: A scabbard 603, which is integrally cast from a superalloy material. The outside of the scabbard mouth position is designed with a sharp edge, and a thick silicon nitride ceramic isolation layer is laid on the inside of the scabbard mouth position. The isolation layer is combined with the matrix through a vacuum diffusion welding process to isolate the temperature exchange between the scabbard 603 and the blade 609. An arc-shaped notch 604 that bends from the scabbard mouth position to the back side is provided at the central axis position on one side of the surface of the scabbard 603. The arc-shaped notch 604 forms an interference fit with the cylindrical rod body of the connecting folding rod 610.

[0039] The blade member includes: The blade 609 uses a tungsten carbide blade with double-sided edge grinding and is slidably connected to the knife sheath 603 through a dovetail groove structure. The cutting edge of the blade 609 is precisely ground to maintain a matching accuracy of 0.02 mm with the sheath opening. The back edge of the blade 609 is formed with a T-shaped contact bracket by electric discharge machining. Three groups of M3 threaded mounting holes are provided on the surface of the contact bracket, and are rigidly fixed to the bent portion of the connecting lever 610 through high-strength bolts.

[0040] As a preferred embodiment, in this embodiment, the transmission assembly 5 includes a main transmission shaft 503 and a secondary transmission shaft 504, which are respectively inserted into the interiors of two collar boxes 601. The secondary transmission shaft 504 is installed in the collar box 601 where the blade member is installed. One end of the secondary transmission shaft 504 is hinged to one end of the main transmission shaft 503. The outer periphery of one end of the secondary transmission shaft 504 is fixed to the inner wall of one end of the trigger sleeve 505. The other end of the trigger sleeve 505 does not contact the inner wall of the collar box 601 where the blade member is installed. The surfaces of the contacting ends of the main transmission shaft 503 and the secondary transmission shaft 504 are fixed to the inner wall of the collar opening of the collar box 601 where the knife sheath member is installed. The other ends of the main transmission shaft 503 and the secondary transmission shaft 504 are jointly and fixedly installed at both ends of the inner wall of the assembly component 3.

[0041] It should be noted that in this embodiment, the transmission assembly 5 realizes the coordinated control of the blade member and the knife sheath member through a double-shaft linkage structure. The main transmission shaft 503 serves as the power input shaft and is driven to rotate by the servo motor 305 and acts on the secondary transmission shaft 504. The main transmission shaft 503 drives the collar box 601 where the knife sheath member is installed and the collar box 601 where the blade member is installed to rotate, thereby realizing the cutting action of the blade 609. At the same time, since one end of the trigger sleeve 505 is fixed to the secondary transmission shaft 504 and the other end does not contact the inner wall of the collar box 601 where the blade member is installed, such a design not only ensures the unique position limitation of the trigger sleeve 505, but also enables the blade 609 to pop out of the knife sheath 603 according to the position of the trigger sleeve 505 under the coordinated action of the main transmission shaft 503 and the secondary transmission shaft 504, ensuring the accuracy and stability of cutting.

[0042] It should be further noted that in this application, conductive tubes 502 are sleeved on the surfaces of the main transmission shaft 503 and the secondary transmission shaft 504. One end of the conductive tube 502 is fixed to the inner wall of the assembly component 3. An insulating cover 501 is sleeved outside the conductive tube 502. An energy supply seat 506 is installed at the position of the conductive tube 502 in the cover body 7. A rigid connecting conductive bundle is installed between the energy supply seat 506 and the conductive cover 605.

[0043] It should be noted that this application supplies power to the energy supply seat 506 through the conductive tube 502, so that the energy supply seat 506 enables the conductive cover 605 to have electric energy through the conductive bundle.

[0044] As a preferred embodiment, in this embodiment, the assembly component 3 includes: A connecting frame 301, which is fitted and fixed to one end outside the crab stick conveyor 2. One side of the top end of the inner wall of the connecting frame 301 is fixedly connected to the secondary transmission shaft 504. On the other side of the top end of the inner wall of the connecting frame 301, a servo motor 305 is installed outside. The shaft body of the servo motor 305 penetrates through the connecting frame 301 and is fixedly connected to one end of the main transmission shaft 503. On the surface of the connecting frame 301 near the position of the crab stick conveyor 2, a splash-proof arc plate 303 for covering the outside of the crab stick conveyor 2 is laid and fixed. A retention notch 304 for the cutting knife body 6 to rotate is left between the two splash-proof arc plates 303. At the bottom end inside the connecting frame 301, a reinforcement arm 302 that fits against the bottom of one end outside the crab stick conveyor 2 is fixed.

[0045] It should be noted that in this embodiment, through the drive of the servo motor 305, the main transmission shaft 503 obtains rotational power, thereby driving the entire cutting knife body 6 to rotate and cut. The setting of the reinforcement arm 302 enhances the stability between the connecting frame 301 and the crab stick conveyor 2, ensuring the stability of the device during the cutting process. The design of the splash-proof arc plate 303 effectively prevents the splashing of crab stick juice or debris during the cutting process, keeping the working environment clean. The retention of the retention notch 304 not only ensures that the cutting knife body 6 has enough space to rotate and cut, but also avoids the interference of the splash-proof arc plate 303 on the movement of the cutting knife body 6, ensuring the smoothness and accuracy of the cutting action.

[0046] Second, to improve a disclosed fluid sandwich crab stick cutting device, a method of using a fluid sandwich crab stick cutting device is also proposed.

[0047] It is worth noting that the method of using a fluid sandwich crab stick cutting device includes: step S100 - step S600.

[0048] Step S100: Start the servo motor 305 to drive the belt conveyor 202 to operate, and convey the preformed fluid sandwich crab stick body 4 to the cutting station. At this time, the gear matching group 205 synchronously drives the pressing roller to radially compress the crab stick.

[0049] Step S200: When the human eye detects that the crab stick is placed on the surface of the belt conveyor 202, the control panel 1 is used to supply electrical energy to the energy supply seat 506 through the conductive tube 502, and supply energy to the cutting edge 609 and the functional seat 608 outside the knife sheath 603 through the conductive bundle to make them operate, so that the cutting edge 609 and the knife sheath 603 reach the working temperature in advance. The working temperatures of the cutting edge 609 and the knife sheath 603 are 120°C ± 5°C and -5°C to 0°C respectively.

[0050] Step S300: When the fluid sandwich crab stick body 4 moves to the cutting station, the servo motor 305 drives the cutting tool body 6 to rotate through the main transmission shaft 503. During the rotation of the tool body, every time the trigger sleeve 505 rotates to the phase angle where it collides with the contact ball, the secondary transmission shaft 504 generates an axial displacement. The mechanical linkage of the axial displacement drives the connecting folding rod 610 to unfold through the insertion rod 611, so that the cutting edge 609 is guided and ejected from the tool sheath 603 under the action of the connecting folding rod 610 and the arc-shaped notch 604, and an effective cutting stroke is formed.

[0051] Step S400: When the cutting edge 609 penetrates the crab stick body, the high-temperature cutting edge makes the surimi protein in the contact area form a dense coagulation layer with a certain thickness. At the same time, the semiconductor cooling module on the inner wall of the tool sheath 603 maintains a low-temperature field of -3°C, so that the viscosity of the surface of the sandwich fluid is increased after cutting, and the cross-section microcapsule encapsulation is realized.

[0052] Step S500: After the cutting is completed, the return spring 612 drives the insertion rod 611 to reset. At this time, the connecting folding rod 610 drives the cutting edge 609 to completely retract into the tool sheath 603 to avoid interference with the subsequent conveyed crab sticks.

[0053] Step S600: After the batch cutting is completed, first cut off the power supply of the servo motor 305. After the tool body completely stops rotating, clean and maintain it. By spraying 82°C sterile pure water into the collar box 601, the residual heat of the tool body is used to perform pasteurization on the contact part.

[0054] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended embodiments and their equivalents.
